Czech subtitle generator

Because Czech and Slovak are so close that a short stretch whose language is guessed may be written the Slovak way, with ä or ô where Czech has none. Set to Czech, every subtitle follows Czech spelling, ř and ů included.

For a video where the speakers switch to Slovak or English for long passages, the main subtitle generator is better: it works out the language of each passage separately.

Long numbers. The same typographic rule keeps “10 kg” and “6 000” on one line. The generator keeps a number with its unit, as with “80 km” and “50 mil”, and keeps the groups of a long figure like “330 000” together.

In our test every figure stayed whole. The numbers themselves already follow Czech style: a space in “330 000”, a decimal comma in “2,4 GHz” and a full stop after an ordinal (“Během 20. let”). A time came back as “ve 23.35”.

With „ “ quotation marks, and a hyphen and a space at the start of each speaker’s line, as in “- Co chceš?” over “- Počkej, dej mi chvilku.”, in Netflix’s Czech style guide. The web generator adds no speaker hyphens.

That guide also keeps lines to 42 characters and reading to 17 characters a second for adults, the same limits as this page, and writes one to ten in words.

Czech is on the list of languages NoteOwl understands on a Mac. It transcribes Czech recordings there with unlimited transcription, tells the speakers apart and saves SRT subtitles with their names. For a Czech transcript to read, use Czech audio to text.
